GB flanged gate valve

Overview: 

A gate valve has a gate plate as its opening and closing component. The movement direction of the gate plate is perpendicular to the flow direction. The gate valve can only be fully opened or fully closed, and cannot be used for regulation or throttling. The gate valve achieves sealing by the contact between the valve seat and the gate plate. Usually, the sealing surfaces are welded with metal materials to enhance wear resistance, such as 1Cr13, STL6, stainless steel, etc. The gate plate has rigid gate plates and elastic gate plates. Depending on the type of gate plate, gate valves are classified as rigid gate valves and elastic gate valves.
